Video coding standards include ITU-T H.261, ISO/IEC MPEG-1 Visual, ITU-T H.262 or ISO/IEC MPEG-2 Visual, ITU-T H.263, ISO/IEC MPEG-4 Visual and ITU-T H.264 (also known as ISO/IEC MPEG-4 AVC), and High Efficiency Video Coding (HEVC) or ITU-T H.265. In 2016, MPEG and ITU-T VCEG formed a joint exploration video team (JVET) to explore new coding tools for the next generation of video coding standards. The reference software is called JEM (joint exploration model).
